Given numbers are 620,715,415,769

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 620,715,415,769 is 5658901820.

Find LCM of 620,715,415,769 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

5 x 124 x 143 x 83 x 769 = 5658901820

Therefore, the lowest common multiple of 620,715,415,769 is 5658901820.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

620 x 715 x 415 x 769 = 141472545500

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

715 : 1, 5, 11, 13, 55, 65, 143, 715

415 : 1, 5, 83, 415

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,715,415,769, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

715:5x 11x 13

415:5x 83

769:769

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 5 = 25

Therefore, the value for common factors is 25.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 141472545500/(1x25)

LCM = 141472545500/25

LCM = 5658901820

Thus, we can understand that the LCM of 620,715,415,769 is 5658901820.
